Ford, Hartsdale, NY., assignor,by mesne assignments, of one-half to International Paper Cornpany, NewYork, N.Y., a corporation of New York, and one-half to The StanleyWorks, New Britain, Conn., a corporation of Connecticut Filed Nov. 12,1958, Ser. No. 773,378 3 Claims. (Cl. 10S-423) rIhis invention relatesto a car liner, and more particularly to a semi-permanent type of carliner for railway cars and other freight vehicles.

In the use of railway boxcars, the inner liners of the car, formedusually of wooden straps or planks, tend to become damaged and theopenings formed in the liners provide avenues for escape and loss ofgranular and other material which may be carried in the cars, while alsoproviding unsatisfactory vehicles for the shipping of case goods andother commodities. Because of such imperfections in the liners, it iscommon for the car to be shipped to a repair point, and there the use ofthe car is lost during a substantial period in which the car is beingrelined.

There has long been a need for some means for relining a car with asemi-permanent structure which can be applied to the car as it stands ona siding so that the car can be immediately put into use, while at thesame time providing such a structure which, when damaged during theshipment of goods, can be readily repaired in situ.

An object of the present invention is to provide a liner of thecharacter described forbringing about the new results above mentioned. Afurther object is to provide a repairable liner which may be readilysecured within a car while at the same time utilizing relatively lightand inexpensive materials. A still further object is to provide in suchliner structure means whereby damage to the liner is avoided through theuse of straps which permit sliding Contact between the liner and cases,etc. being shipped, while at the same time permitting parts of the linerwhich may be damaged to be readily replaced. Other speciiic objects andadvantages will appear as the speciiication proceeds.

The invention is shown, in an illustrative embodiment, by theaccompanying drawing, in which- FIGURE l is a broken perspective view ofthe interior of a railway car equipped with a liner embodying myinvention; FIG. 2, a vertical sectional view; FIG. 3, an enlarged detailsectional view, the section being taken as indicated at line '3f-3 ofFIG. l; and FIG. 4, a broken vertical sectional view, on an enlargedscale, of the liner structure embodying my invention.

In the illustration given, A designates a railway car having a floor 10,a side liner 11 formed of horizontallyextending liner boards, and an endliner 12 shown in the illustration given formed by vertical linerboards. It will be understood that the liners of cars are formed in avariety of ways and may be of any form of construction.

Assuming that the liners 11 and 12 of the car A have been damaged andhave openings therein as illustrated by the numeral 13 in FIG. 2, I findthat the car can be effectively lined through use of the liner structureindicated by the letter B.

The liner B preferably comprises a corrugated board having on its innerside a lining sheet 14 and on its outer side a lining sheet 15, the twosheets being adhesively bonded to a corrugated core 16. Against theouter sheet 15 I place metal straps 17 which are preferably providedwith spaced nail openings 18 extending continuously therethrough, andthe straps 17 are preferably held in position and in spaced-apartrelation by an outer web 19 which may be a paper sheet and which isadhesively bonded to the sheet 15 and about said straps 17. By bondingthe web 19 about the straps 17, it is found that the straps are held inthe spaced-apart position shown, while the board B is being shipped andhandled and until the board can be eitectively installed in positionupon the liner of the car.

The liner B may be installed upon the car liner 11 or 12 yby placing thesame upon the car liner and driving nails through the nail openings 18,the nails extending through the structure B and into the car liner 11 or12. .lWhere the liner B passes around a corner of the car, the liner Bmay be readily bent into the desired position by passing a scoring tool(preferably a scoring roller) along the liner portion adjacent thecorner so as to crush the inner core 16 at the point of bend. When thecore is crushed at this point, the liner B can be bent readily to theposition shown in FIG. 3 and the flexible metal strap 17 also permitssuch bending. Nails may be secured to the liner B about the cornerportions, or one corner portion of the member B, to hold the structuretightly within the corner portion of the car.

While I have referred to the straps 17 as formed of flexible metal7 itwill be understood that `these may be formed of plastic, iiberglass, orany other suitable material effective for the purposes which will belater described and particularly for the purpose of providing skidtracks along which objects carried within the car may slide underconditions of impact without damaging the structure of the liner B.

While the corrugated board has been shown mounted in a horizontalposition within the car and with the straps running also horizontally ofthe car, it will be understood that the board and straps may be mountedso that the straps run vertically of the car and the strap-equippedboardmay extend all the way from the top of one side of the car downwardlyover the bottom of the car and upwardly to the top of the other side ofthe car. I prefer the structure in which the straps run horizontallybecause of their value in protecting the board structure and alsoprotecting articles slidably engaging the straps.

The board structure may be employed with a car frame or with a car framehaving wooden liner boards thereon. For example, in originalconstruction, the wooden liner boards may be omitted, `and thestrap-equipped corrugated board may be secured directly to the innerframe of the car consisting of vertical wooden studs or metal studsequipped with nailing strips, etc. Thus, the structure herein may beemployed in original construction or for renewing a car having an innerframe lining or such a frame provided with a wooden board lining whichhas been damaged.

While I have described the liner B as being formed of corrugated board,it will be understood that corrugated pulpboard, laminated or reinforcedsheets, or plastic sheets may be employed which will provide the supportand strength necessary to protect the commodity loaded in the car, whileat the same time supporting the straps in spaced, eective positionduring the shipping of the goods. Corrugated pulpboard is very usefulbecause it is thicker 'than paper, and even if the outer layer becomestorn, the corrugated medium and inner liner still remain intact toprotect the commodity.

In the operation of the liner B, it is found that a case or other ladingarticle designated by the numeral 20 in FIG. 2, upon striking the linerB during a sudden starting or stopping of the car A, tends to engage thestraps 17 and to glide or slide along the straps without digging intoand injuring the liner B. In this operation, the yielding boardstructure facilitates the action of the slide members 17 in permittingsliding movement of the case 20 without causing it to dig into andinjure the liner B. Such sliding movement is further facilitated by theweb or paper sheet 19 on the outside of the liner B. At least until thesheet 19 is torn away or destroyed, the sheet serves a useful functionin allowing the case 20 or other article being shipped to slide readilyover the straps 17. I have already referred to the function of the outersheet 19 in confining the straps 17 in spaced-apart position until theyare secured upon the car liner 11 or 12 by nails, etc., and it is nownoted that such a web or sheet serves the further function offacilitating slippage of a case or other object along the straps 17 inthose cases where sudden deceleration or acceleration of the car Aoccurs.

Should the liner B be damaged at some time through Contact with somearticle that is being conveyed, and openings, as indicated by thenumeral 21, formed in the corrugated board, the area can be readilyrepaired by placing a corrugated board strip 22 behind the damaged areaand secured to the remainder of the corrugated board of the liner B bymeans of adhesive tape, adhesive, or any other suitable material.

While, in the illustration given, l have set forth a specic structure inconsiderable detail for the purpose of illustration, the details ofstructure therein may be varied widely by those skilled in the artwithout departing from the spirit of my invention.
